Recent model consensus and official local forecasts position 27–29°C as the most probable range for São Paulo’s September 25 high, with 28°C carrying the strongest market-implied odds. Clearing skies after several days of overcast, cooler conditions (highs near 20°C or below) and light winds are expected to allow rapid daytime warming, consistent with GFS guidance showing a peak near 28°C and Brazilian meteorological updates projecting 26–28°C under mostly sunny afternoon skies. Historical September averages near 23–25°C provide context for the current elevated readings. Updated model runs and real-time observations on the day will determine final resolution within the narrow 27–29°C window.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=sbgr
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
